High Altitude Mountain Weather Forecasting Services
We provide forecasts for most major climbing venues:
Why Our Forecasts Are Unique and Accurate :
We review a minimum of 6 forecast models and many more at times. This takes more time but the accurate results are well worth it. We know of no other forecasts that are produced with this detail and time commitment.

Being a mountaineer, I know the value of precise detailed forecasts and I know the type of content climbers want.

Each forecast uses a weighted average of the forecast models based on the accuracy of each forecast model.

After each forecast is made, it is analyzed with actual weather conditions to determine the accuracy of each forecast and what needs to be done to improve each forecast.

“Our expedition took place in a somewhat ‘uncharted’ season on Everest, the post-monsoon. The weather during the autumn is significantly less observed than in the spring. Your forecasts were excellent and that is not an easy task when forecasting from October 1 till November 1. Not only was I impressed with these forecasts but also our climbing Sherpas’ found your forecasts very valuable and that was the first time they liked an “outsider’s” forecasts.”
